what is this?

I have no idea what this is and how much it would be worth. I can make out the hall mark as "t & t a drum underneath with e on one side and p on the other then under drum NS and the numbers 57-66. It is missing the plug that twists on and the top has a cork underneath it? I have no idea, but find it interesting. Is it worth anything and what is it? Help It is like a t pot with a small spout with a lid that has a cork underneath. Mainly I would like to find the manufatuerer hallmark. I can not reduce my pictures, I am a novice.
